This is probably obvious to all of you, but taken me days to get this working (and still not sure how!).

Inside an Entity I have an internationalised enum (as I am hoping to persist a value of its kind with the Entity):

@SuppressWarnings("serial")
@Entity // Defines this as an Entity that is a class mapped toDate the Datastore.
@Name("booking") // Name used within SEAM for an instance of this class.
public class Booking implements Serializable {

 public enum OrganisationKind {
 PRIVATE_BOOKING ("booking_private"),
 PRIVATE_BOOKING_OPEN ("booking_private_open"),
 NON_PROFIT_ORG ("booking_non_profit_org"),
 COMMERCIAL ("booking_commercial_org"),
 OPEN_EVENT ("booking_open_event"); // Only booked by Selwyn Equestrian Staff
 private final String inlLabel;
 OrganisationKind(String inlLabel) {
 this.inlLabel = inlLabel;
 }
 public String getInlLabel() { return inlLabel; }
 }

...
 private OrganisationKind organisationKind;
...

I have a controller that requires this enum to be displayed as selectOneRadio... these routines handle the selection:

 public Map getOrganisationKindList();

 public Booking.OrganisationKind getSelectedOrganisationKind();

 public void setSelectedOrganisationKind(Booking.OrganisationKind orgKind); not use I need this one as the Change fires ok

 public void selectedOrganisationKindChanged(ValueChangeEvent event);

The Impl:

...
 /**
 * The currently selected Booking Type
 */
 private Booking.OrganisationKind selectedOrganisationKind;

...

 public Map getOrganisationKindList() {
 Map<String,Booking.OrganisationKind> choices = new HashMap<String,Booking.OrganisationKind>();
 for (Booking.OrganisationKind type : Booking.OrganisationKind.values()) {
 choices.put(messages.get(type.getInlLabel()), type);
 }
 return choices;
 }

 public Booking.OrganisationKind getSelectedOrganisationKind() {
 return selectedOrganisationKind;
 }

 public void setSelectedOrganisationKind(Booking.OrganisationKind orgKind) {
 this.selectedOrganisationKind = orgKind;
 }

 public void selectedOrganisationKindChanged(ValueChangeEvent event) {
 if (event.getNewValue() != null) {
 Booking.OrganisationKind theOrganisationKind = Booking.OrganisationKind.valueOf(event.getNewValue().toString());
 selectedOrganisationKind = theOrganisationKind;
 } else {
 log.error("null new event passed in. Error!");
 }
 }

The screen shows all this using:

<ice:panelGrid columns="1" styleClass="center">
 <ice:selectOneRadio
 value="#{availabilityController.selectedOrganisationKind}"
 valueChangeListener="#{availabilityController.selectedOrganisationKindChanged}"
 partialSubmit="true"
 layout="pageDirection"
 converter="#{enumTypeConverter}">
 <f:selectItems value="#{availabilityController.organisationKindList}"/>
 </ice:selectOneRadio>
</ice:panelGrid>

Now... I have to provide a Converter (no idea if this is right.. and the screen seems to find this without outjecting it to the view at all!!):

@Intercept(InterceptionType.NEVER)
@SuppressWarnings("serial")
@Stateless // A new component is created or re-initialised and re-used each time it is called.
@Name("enumTypeConverter") // Name used within SEAM for an instance of this class.
// All stateless session beans belong to the Stateless Context Scope
public class EnumTypeConverterImpl implements EnumTypeConverter {

 @SuppressWarnings("unchecked")
 public Object getAsObject(FacesContext context, UIComponent comp, String value) throws ConverterException {
 Class enumType = comp.getValueBinding("value").getType(context);
 return Enum.valueOf(enumType, value);
 }

 public String getAsString(FacesContext context, UIComponent component, Object object) throws ConverterException {
 if (object == null) {
 return null;
 }
 Enum type = (Enum) object;
 return type.toString();
 }

}

Anyhow, it may help some poor sap in the future!

FINALLY GOT TO USE INTERNATIONALISED ENUMS!!!


From the screen:

O open booking (Selwyn Equestrian Centre staff only)
O commercial booking (e.g. NZ Elite Horse Auctions Ltd.)
O private booking but open to anyone (cost is per horse - max of 4 places)
O non profit booking (Dressage Canterbury etc.)
O private booking (cost is for Arena) <<---Selected


Result (on screen and in controller) = PRIVATE_BOOKING
